摘要

设计了一块球面-非球面柱透镜, 用于将高斯圆斑整形为平顶线斑。通过编写Zemax编程语言批量添加操作数与设置默认优化函数优化结合的方法完成设计, 并与性能参数相同的非球面透镜-柱透镜组进行比较, 同时分析了球面-非球面柱透镜最后一面到像面距离的不同对线斑长宽比和平顶度的影响。与非球面透镜-柱透镜组相比, 线斑尺寸相同但平顶度一般(边缘处约下降10%), 在一定范围内调整最后一面到像面的距离可使平顶度变好(可达到90%), 但会使长宽比变小(由88.33降至20.38)。所得结果表明, 若要获得能量均匀分布的线斑, 在长宽比可调整的范围内, 球面-非球面柱透镜的设计可以简化光束整形系统结构, 满足轻量化的要求, 是一种可行的方法。

Abstract

To convert Gaussian spot into flat line spot, a spheric-aspheric cylindrical lens is designed. The design is accomplished by using Zemax programming language to set operands and default optimization function. The design is compared with the aspheric lens-cylindrical lens group with the same performance parameters. The influence of the distance from the last surface to the image surface of the spherical-aspherical cylindrical lens on the length-width ratio of the linear spot and the flatness of the line-focused is analyzed. Compared with the aspheric lens-cylindrical lens group, the line spot size is the same but the flatness is normal (about 10% decline at the edge). Adjusting the distance from the last surface to the image surface in a certain range can make the flatness better (can reach 90%), but the aspect ratio is reduced (from 88.33 to 20.38). The results show that, in order to obtain the line spot with uniform distribution of energy, in the adjustable range of length-width ratio, the design of spheric-aspheric cylindrical lens can simplify the structure of beam shaping system and meet the requirements of lightweight. It is a feasible method.
